The Chandler man accused of branding his initials into his girlfriend's vagina has been arrested again, this time for allegedly having sex with a dog.

The Maricopa County Sheriff's Office says detectives served a warrant on 47-year-old Christopher Lynn Jackson's house yesterday, and recovered videos that "clearly show" Jackson and two women "performing various sex acts with a male German Shepherd."

The Sheriff's Office says the information about the alleged bestiality came as a result of Jackson's arrest for using hot irons to brand his initials into his girlfriend's vagina.

New Times first reported the allegations against Jackson. The ex-girlfriend told investigators that Jackson took her to a baseball game back in May, and after the game, Jackson wanted to go dancing. The woman told Jackson she was too tired to do that. He "offered her a pill to energize her," according to court documents.

Not feeling energized after taking the pill, Jackson gave her two more. The woman passed out shortly after taking the other two pills, according to court documents.

She woke up in Jackson's bed in severe pain, and discovered that Jackson had branded her. She said she saw Jackson with the branding equipment and butane torch, according to the documents.

The woman told police that Jackson "bragged" to her that he'd done that to other girlfriends in the past and explained to her that he wanted to do the same thing to her because "her vagina was his," court documents state.

Although Jackson did not speak to police after being arrested, police did serve a search warrant and recovered the branding tools and butane torch.

The Sheriff's Office didn't disclose what exactly led to detectives' discovery that Jackson -- the owner of a landscaping company called Lawn Tamers, as well as a ballroom-dancing studio -- allegedly engaged in bestiality.

Detectives also arrested one of the women seen in the dog-sex video, 61-year-old Josephine Erikson, who was "seen in the videos orally copulating and engaging in intercourse with the dog," MCSO says.
